passive smoking.....serious health problems..

many smokers will argue that smoking is their right and they can do watever pleases their bodies.they dont realize that smoking affects the people around them as well.passive smoking can have serious affects on a persons health like cancer,heart disease,repiratory disease,ear infection,low birth weight,asthma....list continues.we move around public places and find people smoking, who never realizes that they are not alone.they are not only causing serious problems to themselves but also to the people around them.
what do you people have to say about it..????
